Emile, I agree with you that may be some of the alien felt scare to visit the earth. But some of them may be felt very challenging to see 'we' cause we human creature has different face and body if compare with them. Haha... they want to examine us, just like what our scientist will do to them.

This is really very interesting if we can be friend with aliens..., of course I mean be friend with good alien and not bad alien... like this ''

Hello! I am Theeraphat Poomalee. I am very interested in all topics about aliens and UFOs. There are a lot of questions which ask about aliens, but they are still in doubt. There are few data to make them clear. I think that aliens and their UFOs probably exist because of these reasons. First, the universe is very large and it consists of many stars which are likely proper for forming life. Second, though, possibility for life forms to be created is very tiny, but they are not equal to zero. Since we calculate this possibility with a lot of stars in universe, the result is still not less. But it seems to be so far from us that we can reach them. Moreover, according to science concept, we should prove something before we believe it. I agree with this. But something that we are still unable to prove it, we should not infer that it does not exactly exist, so the truths about the aliens are negligible. Eventually, if they are intelligent, they can create their transport like us. But I wonder if they can reach the earth . In conclusion, I believe in aliens and UFOs, though I have never seen them myself. I wish that they would be friendly.
